Hey guys,
Im designing a full differential op amp in cadence and want to test the slew rate. Therefore i configured it as a unity gain buffer using feedback resistors. After applying a large signal input step i notice that there is a Dc offset. If i apply a positive input step it doesnt start at 0 Volts where it should be. Same goes if i apply a negative step. Im pretty unexperienced and would like to know the reason
